IMPROVEMENT IN ROLLS FOR HO-RSESHOE BARS AND B LANKS.

I Specification forming part of Letters Patent No. 219,621, datedSeptember 16, 1879 application filed May 14, 1879.

To all whom it may concern:

Beit known that I, LOUIS G. CLAUDE, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Rolls forHorseshoe Bars and Blanks, of which the following is a specification.

This invention relates to rolls for fullering or creasing the blanks forhorseshoes, and for producing the indentations at the points in thecreases where the nail-holes are to be punched, and these rolls may beemployed in producing plain blanks or those having solid calks.

Bars and blanks have h eretofore been creased and provided with calks byrolling, and I make no claim to this, broadly, or to the employment ofsimple rolls for this purpose; but, by means of my improved rolls, thecreases may be sunk obliquely into the face of the web, and with avarying obliquity, so as to give the proper direction to the nails atdifierent parts of the hoof, all as will be more particularlyhereinafter set forth.

In the drawings which serve to illustrate my invention, Figure 1 is afront elevation of a pair of my improved rolls; and Fig. 2 is atransverse section of the same 011 a smaller scale, taken in the planeof the line wwin Fig.

1. Fig. 3 is a detached plan, full size, showing the ereaser; and Fig. 4shows sections taken through the same at the points indicated by thelines y y and 22. Fig. 5 shows a section of the blank, taken through thecrease in the web.

A represents a suitable frame or support for the rolls, and B B- are theroll-mandrels, provided with fixed collars era. The upper roll hashearings in boxes adapted to be adjusted vertically by means ofscrews 1) b, in the usual way.

O is the upp-r and D the lower roll. These slide on spline: on theroll-mandrels, and are pressed firmly up to their respective fixedcollars by means of tubular sleeves E E and nuts F F. The lower roll, D,has two fixed side flanges, c 0, arranged perpendicular to the axis, andso as to embrace the upper die and the blank or bar, and an obliqueconical face, 61, 011 which the bar or blank rests while it isundergoing the rolling operation. The upper roll, 0, has a coned orbeveled face, 6, arranged substantially parallel to the similarly-conedface of the roll D when both are in position. On this conical face 0 areraised the creasers f f, provided with elevations g g, to produceindentations for the nail-holes. The axes of rotation of the two rollsare-substantially parallel with each other.

Owing to the obliquity of the faces of the rolls, the bar to be creasedis passed between them, with its upper and lower faces inclined, as willbe readily understood but the creases are sunk in the face of the webobliquely with the same for the whole or a portion of their length, aswill be seen at 42 in Fig. 5.

The plane of the inner face, j, (see Fig. 5,) of the bar or blank iskept at right angles to the plane of the upper and lower faces of thesame by means of a fillet, k, Fig. 1, arranged at the re-entering anglemade by the junction of one of the flanges c of the lower roll with theface d of the said die.

In Figs.'3 and4 I have shown, on a large scale, the peculiarconstruction and form of the creaserf. The inner face of this creaser iswarped or variably inclined. At the toe end I of the creaser the faceisperpendicular to the axis of the rolls, as shown in the section to theleft in Fig. 4. At the heel end an it is more nearly perpendicular tothe face 0 of the roll, and between these extremes it varies ininclination, as will be seen. This has the effect of throwing theheel-nails nearer to the outer edge of the blank than those at the toe,and also gives the nails at this point a more nearly perpendiculardirection into the hoof. The object of this is to give the nails, inshoeing, a depth of hold and a direction come I sponding to the peculiarshape of the hoof.

It is well known that the hoof-wall is thicker at the toe than at theheel, and makes a more acute angle with the plane, of the sole. In deed,the walls where the heel-nails are driven are nearly vertical. Thismakes it important that the angles at which the nails are driven shouldvary in accordance with the slope-of the hoof.

In addition to the creasers, the roll 0 may be provided with suitablerecesses to form the toe and heel calks, and one or more ribs or bladesh, to indicate the dividing-lines between the shoe-blanks in the bar.These may, however, be omitted in some cases.

In the drawings I have shown the roll 0 provided with two sets ofcreasers; but it is obvious that by increasing or reducing its diameterone or more sets may be provided thereon, as desired.

These rolls may be driven by connecting them with the bar-rolls orindependently, as found most convenient. 1

Having thus described my invention, what I claim as new is- 1. Thecombination of the roll 0, provided with a conical or oblique face, 0,and creaser f, with the roll D, provided with flanges c 0, a

conical or oblique face, d, and a fillet, is, all substantially as andfor the purposes set forth.

2. The creasing-(lief mounted on or formin g a part of the oblique orconical face of the roll 0, its inner face being in a warped planevarying in its inclination or angle with the axis of rotation from Z tom, substantially as shown in Figs. 3 and 4, and for the purposes setforth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

LoUIs e. CLAUDE.
